Imagine you do a test cross between a purple-flowered pea plant having serrated leaves (both dominant traits) and a white-flowered pea plant having smooth edges
If the purple-flowered plant is heterozygous for both traits, the expected ratio in the offspring is 1 purple-serrated:1 purple-smooth:1 white-serrated:1 white-smooth. Instead, you see 7 purple-serrated:1 purple-smooth:1 white-serrated:7 white-smooth. What is the explanation of this ratio? A) There has been a mutation during the cross. B) There is incomplete dominance. C) The genes are linked. D) The genes are sex-linked and inherited by incomplete dominance.
